2005 4.0 that I recently had the transmission rebuilt. After it didn’t seem right. It has progressed to multiple o2 sensor issues. I started with misfire on 1 so we changed the plugs. Multiple misfires now. It is running extremely rich. I was leaning to replacing the o2 sensors on bank 1 where the initial o2 stuck on lean started. Could the sensor 2 been swapped and lead to the issues that have developed. Sensor 1 is plugged in correctly. I did clean the MAF with no improvement.
